I bought this for my wife because she is a teacher who facilitates hundreds of meetings a year. Love the brand just not the style sandal. 3) No wifi calling but never used it anyways. i ordered the 14 for my son and they are more like a 12 . Update: I ordered a size 7-8 just to compare the feel. I have plantar facitus in one foot and a heel spur in the other. Fortunately they all arrived and didnt damage the rail in the box. I dont feel comfortable trying to put them back on because I feel the entire thing will fall apart. Our granddaughter loves these and wore them all day yesterday, on receipt. This isnt a problem on airplanes (because it tends to be so cold) but out and about I did notice it.
